Abstract

The invention relates to a preparation method for a nano-structure strontium borate SrB6O10 / 5H2O:Eu<3> luminous material. According to the invention, the strontium borate is uniform in shape and adopts a nano structure assembled by nanosheets, and the thickness of each of the nanosheet is 100 nm; and analytic reagents SrOH2 / 8H2O, Na2B4O7 / 10H2O, H3BO3 and EuNO3, which are purchased through commercial sources, are taken as main raw materials, and a simple water solution reaction method is adopted to prepare the material under the assistance of additives at the temperature of 50-80 DEG C. The method is simple and low in reaction temperature. The strontium borate SrB6O10 / 5H2O:Eu<3> luminous material is high in color purity and in rare earth ion quenching concentration, and strong in Eu<3> stability compared with an anhydrous strontium borate substrate luminescent material SrB6O10:Eu<3>, and can be applied to the fields of development displaying, light sources and the like.
